The Lend-Lease Act

In September 1940, President Roosevelt negotiated the famous destroyer-for-bases agreement under which 50 obsolete "four-pipers" US WWI destroyers were exchanged for 99-year lease of several British bases in the Western Hemisphere. This was rationalized that these bases might one day become critical to US defences.

The Lend-Lease Act is born

The Lend-Lease Act was approved in March 11, 1941 by the Congress. This act gave President Roosevelt almost unlimited freedom in directing supplies, tanks, aircraft and ammunition to the war effort in Europe without sacrificing US neutrality at that time. One of the aspects of the Lend Lease Act were SAM ships, Liberty ships lent to Britain.

When the war had ended the Lend-Lease programme had extended over $41 billion in aid to more than 40 nations (some sources say the aid was as high as $50 billion). Britain got the biggest share or roughly $30 billion and the Soviets about $11 billion. China got $1 billion.

Less than $10 billion of that aid was ever repaid, making this appear more like the donation and support it really was.

Lend-Lease assistance to the USSR

Lend-Lease was the most visible sign of wartime cooperation
between the United States and the Soviet Union. About $11
billion in war matériel was sent to the Soviet Union under that
program. The program started 3 months after the German invasion of USSR in June, 1941.

Additional assistance came from U.S. Russian War Relief
(a private, nonprofit organization) and the Red Cross. About
seventy percent of the aid reached the Soviet Union via the
Persian Gulf through Iran; the remainder went across the Pacific
to Vladivostok and across the North Atlantic to Murmansk. Lend-
Lease to the Soviet Union officially ended in September 1945.

Joseph Stalin never revealed to his own people the full
contributions of Lend-Lease to their country's survival, but he
referred to the program at the 1945 Yalta Conference saying,
"Lend-Lease is one of Franklin Roosevelt's most remarkable and
vital achievements in the formation of the anti-Hitler alliance."

Lend-Lease mat&eacuteriel was welcomed by the Soviet Union, and
President Roosevelt attached the highest priority to using it to
keep the Soviet Union in the war against Germany.
Lend-Lease helped the Soviet Union push the
Germans out of its territory and Eastern Europe, thus
accelerating the end of the war. With Stalin's takeover of
Eastern Europe, the wartime alliance ended, and the Cold War
began.
